Exchange 2013 CU2 will not install, Exchange is now in an unuseable state.

Question

I have downloaded Exchange 2013 CU2 and attempted to install it from a local drive.  Exchange 2013 is installed on a Server 2012 Standard VM in Hyper-V.  I ran the two following commands before trying to install
setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms
setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms
Upon trying to run the installer, I recieve the following error.
Error:
The following error was generated when "$error.Clear();
                    & $RoleBinPath\ServiceControl.ps1 EnableServices Critical
                " was run: "AuthorizationManager check failed.".
During my first install attept, the error was on step 4 of 15. I have tried to rerun the setup with no luck.  I noticed the installer leaves all the Exchange services disabled, as well as winmgmt, remoteregistry, w3svc, iisadmin.  These four services
are the critical services the errors refer to.  I have verified my execution policy is correct
PS C:\Windows\system32> Get-ExecutionPolicy -list
Scope                                            
ExecutionPolicy
MachinePolicy                                               
Unrestricted
UserPolicy                                                  
Undefined
Process                                                  
Undefined
CurrentUser                                                  
Undefined
LocalMachine                                               
RemoteSigned
Upon trying to rerun the setup, I have ran the following commands in order to start the critical services manually
Get-Service-name
winmgmt,
remoteregistry,
w3svc,
iisadmin
|
set-service -startuptype
automatic
Get-Service-name
winmgmt,
remoteregistry,
w3svc,
iisadmin
|
Start-Service
No matter what I do, the Exchange 2013 CU2 installer seems to fail.  I'd appreciate any possible help with this.
Thanks,
Chris
To add to what I posted, I also have the following error in the event log.

I also have these two errors in event viewer that keep occuring. 
Event 2280, IIS-W3SVC-WP
The Module DLL C:\Program Files\Microsoft\Exchange Server\V15\Bin\kerbauth.dll failed to load.  The data is the error.
Event 2300, IIS-W3SVC-WP
The
worker process cannot access the CLR configuration file at 'C:\Program
Files\Microsoft\Exchange
Server\V15\bin\GenericAppPoolConfigWithGCServerEnabledFalse.config'. 
Verify that the file exists and that the worker process has read access
to the file.

Answer 1

I kept quickly running the following two commands while the install was happening
Get-Service-name
winmgmt,
remoteregistry,
w3svc,
iisadmin
|
set-service -startuptype
automatic
Get-Service-name
winmgmt,
remoteregistry,
w3svc,
iisadmin
|
Start-Service
This caused the install to succeed.
